Phantom Tech Stack

Crypto wallet and infrastructure platform built on Solana, Ethereum, and Bitcoin

Software Development San Francisco, CA 51–200 employees Founded 2021 Privately Held

Phantom operates a multi-chain crypto wallet and platform engineered on Solana, Ethereum, Bitcoin, and Polygon with a technology stack built for scale: Kubernetes on AWS EKS, Kafka, Flink, Spark, and PostgreSQL. The company is actively extending beyond a single-chain wallet—projects include support for additional blockchains, backend infrastructure for a stablecoin product (Phantom Cash), and complementary protocol-layer products. The hiring mix is heavily weighted toward senior engineering (20 of 33 open roles), with smaller marketing, design, and security teams, indicating product-focused expansion rather than sales-driven growth.
